Determinants of Digital Health Literacy Among Hypertensive Adults: A Community-Based Cross-Sectional Study.
Article in Journal of primary care & community health. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveDigital health literacy (DHL) is a critical component for the effective self-management and secondary prevention of hypertension. However, the multi-level determinants of DHL in community settings are not yet fully understood. This study aimed to assess the status of DHL and identify its key sociodemographic, psychosocial, and health system determinants among adults with hypertension in China.
methodsA cross-sectional survey was conducted (October 2024-January 2025) across 1 tertiary general hospital and 3 community health service centers in Changzhou, China. Data were collected from 660 hypertensive adults using a structured questionnaire, including the eHealth Literacy Scale (eHEALS), and scales for physician-patient interaction, perceived internet health information quality, and perceived family support. Determinants were analyzed using multivariate logistic regression and a random forest model to rank factor importance.
resultsNearly half of the participants (49.45%) demonstrated low DHL. Multivariate logistic regression indicated that older age (specifically ≥75 years: OR = 13.33, 95% CI = 1.73-99.88), limited internet use (<1 h/day: OR = 2.50, 95% CI = 1.04-5.88), and concerns regarding data privacy (OR = 3.42, 95% CI = 1.01-11.58) were significant predictors of low DHL. Additionally, higher perceived quality of internet health information (OR = 0.72, 95% CI = 0.67-0.78), better physician-patient interaction (OR = 0.92, 95% CI = 0.86-0.99), and greater family support (OR = 0.37, 95% CI = 0.25-0.55) were associated with lower odds of low DHL. The random forest model identified the perceived quality of internet health information as the most influential predictor, followed by age and data privacy.
conclusionDHL levels among individuals with hypertension in the community are suboptimal. These findings highlight the potential importance of a multilevel approach to supporting DHL. Efforts to improve the perceived quality of internet health information and strengthen social support systems may be beneficial, and primary care providers could play an important role in guiding patients' use of digital health resources.
